Review on Blackview BV5500 Plus 4G Rugged Unlocked Cell Phones - Waterproof, Drop Proof, 5.5” 3GB+16GB Dual SIM [Quad Core] Android 9, 4400mAh Battery, Face ID Mobile Phones (Black) by Brian Campbell

As a retired Marine I was impressed with the product's durability and "reliability". Because of the discount, very discount, I tried the service provider. I switched back to my original provider and it was loud and clear. In fact, the clarity and volume of the sound is much better than my previous phone. In general, the reliability of a phone reflects the quality of the product. It's under control. Highly recommended for those spending time outdoors, leading an active lifestyle or just want a quality product that lasts.
